      fix regression in approval-voting introduced in #3747 (#3831) · 3fc5b826
      ordian authored 
      

Fixes #3826.

The docs on the `candidates` field of `BlockEntry` were incorrectly
stating that they are sorted by core index. The (incorrect) optimization
was introduced in #3747 based on this assumption. The actual ordering is
based on `CandidateIncluded` events ordering in the runtime. We revert
this optimization here.

- [x] verify the underlying issue
- [x] add a regression test

      XCM Fee Payment Runtime API (#3607) · 3c972fc1
      Pavel Orlov authored 
      The PR provides API for obtaining:
- the weight required to execute an XCM message,
- a list of acceptable `AssetId`s for message execution payment,
- the cost of the weight in the specified acceptable `AssetId`.

It is meant to address an issue where one has to guess how much fee to
pay for execution. Also, at the moment, a client has to guess which
assets are acceptable for fee execution payment.
See the related issue
https://github.com/paritytech/polkadot-sdk/issues/690.
With this API, a client is supposed to query the list of the supported
asset IDs (in the XCM version format the client understands), weigh the
XCM program the client wants to execute and convert the weight into one
of the acceptable assets. Note that the client is supposed to know what
program will be executed on what chains. However, having a small
companion JS library for the pallet-xcm and xtokens should be enough to
determine what XCM programs will be executed and where (since these
pallets compose a known small set of programs).
```Rust
pub trait XcmPaymentApi<Call>
	where
		Call: Codec,
	{
		/// Returns a list of acceptable payment assets.
		///
		/// # Arguments
		///
		/// * `xcm_version`: Version.
		fn query_acceptable_payment_assets(xcm_version: Version) -> Result<Vec<VersionedAssetId>, Error>;
		/// Returns a weight needed to execute a XCM.
		///
		/// # Arguments
		///
		/// * `message`: `VersionedXcm`.
		fn query_xcm_weight(message: VersionedXcm<Call>) -> Result<Weight, Error>;
		/// Converts a weight into a fee for the specified `AssetId`.
		///
		/// # Arguments
		///
		/// * `weight`: convertible `Weight`.
		/// * `asset`: `VersionedAssetId`.
		fn query_weight_to_asset_fee(weight: Weight, asset: VersionedAssetId) -> Result<u128, Error>;
		/// Get delivery fees for sending a specific `message` to a `destination`.
		/// These always come in a specific asset, defined by the chain.
		///
		/// # Arguments
		/// * `message`: The message that'll be sent, necessary because most delivery fees are based on the
		///   size of the message.
		/// * `destination`: The destination to send the message to. Different destinations may use
		///   different senders that charge different fees.
		fn query_delivery_fees(destination: VersionedLocation, message: VersionedXcm<()>) -> Result<VersionedAssets, Error>;
	}
```

      westend: `SignedPhase` is a constant (#3646) · 0c15d887
      Bastian Köcher authored 
      

In preparation for the merkleized metadata, we need to ensure that
constants are actually constant. If we want to test the unsigned phase
we could for example just disable signed voter. Or we add some extra
mechanism to the pallet to disable the signed phase from time to time.

      Migrate parachain swaps to Coretime (#3714) · 90234543
      Tsvetomir Dimitrov authored 
      This PR notifies broker pallet for any parachain slot swaps performed on
the relay chain. This is achieved by registering an `OnSwap` for the the
`coretime` pallet. The hook sends XCM message to the broker chain and
invokes a new extrinsic `swap_leases` which updates `Leases` storage
item (which keeps the legacy parachain leases).

I made two assumptions in this PR:
1.
[`Leases`](https://github.com/paritytech/polkadot-sdk/blob/4987d7982461e2e5ffe219cdf71ec697284cea7c/substrate/frame/broker/src/lib.rs#L120)
in `broker` pallet and
[`Leases`](https://github.com/paritytech/polkadot-sdk/blob/4987d7982461e2e5ffe219cdf71ec697284cea7c/polkadot/runtime/common/src/slots/mod.rs#L118)
in `slots` pallet are in sync.
2. `swap_leases` extrinsic from `broker` pallet can be triggered only by
root or by the XCM message from the relay chain. If not - the extrinsic
will generate an error and do nothing.

As a side effect from the changes `OnSwap` trait is moved from
runtime/common/traits.rs to runtime/parachains. Otherwise it is not
accessible from `broker` pallet.

Closes https://github.com/paritytech/polkadot-sdk/issues/3552

      [subsystem-benchmarks] Save results to json (#3829) · fd79b3b0
      Andrei Eres authored 
      Here we add the ability to save subsystem benchmark results in JSON
format to display them as graphs

To draw graphs, CI team will use
[github-action-benchmark](https://github.com/benchmark-action/github-action-benchmark).
Since we are using custom benchmarks, we need to prepare [a specific
data
type](https://github.com/benchmark-action/github-action-benchmark?tab=readme-ov-file#examples):
```
[
    {
        "name": "CPU Load",
        "unit": "Percent",
        "value": 50
    }
]
```

Then we'll get graphs like this:

Let me know if this structure is adequate.

**Note:** The usage of the words `Merkle`, `Merkelize`, `Merklization`,
`Merkelization`, `Merkleization`, is somewhat inconsistent but I left it
as it is.

~~**Note:** In some places the term `Receival` is used to refer to
message reception, IMO `Reception` is the correct word here, but I left
it as it is.~~

~~**Note:** In some places the term `Overlayed` is used instead of the
more acceptable version `Overlaid` but I also left it as it is.~~

~~**Note:** In some places the term `Applyable` is used instead of the
correct version `Applicable` but I also left it as it is.~~

**Note:** Some usage of British vs American english e.g. `judgement` vs
`judgment`, `initialise` vs `initialize`, `optimise` vs `optimize` etc.
are both present in different places, but I suppose that's
understandable given the number of contributors.

~~**Note:** There is a spelling mistake in `.github/CODEOWNERS` but it
triggers errors in CI when I make changes to it, so I left it as it
is.~~
